OK,x,y.yy/
Reads the pump’s current pressure and flowrate, where:
(x, xx, xxx, or xxxx)
x, xx, xxx, or xxxx = current pressure in psi
(y.yyy, y.yy, yy.yy, or yy.y) y.yyy, y.yy, yy.yy, or yy.y = flow rate in mL/min.
The format is y.yy and yy.yy for a standard pump head,
y.yyy for micro pump head or yy.y for a macro pump head.
CS
OK,x.xx,y,z,PSI,w,v,u/
Reads the current pump setup, where:
(x.xxx, xx.xx, or xxx.x)
x.xxx, xx.xx, or xxx.x = flow rate in mL/min.
(y, yy, yyy, or yyyy)
y, yy, yyy, or yyyy = upper pressure limit
(z, zz, zzz, or zzzz)
z, zz, zzz, or zzzz = lower pressure limit
PSI = Units (psi, atm, mpa, bar)
w = pump head size (0 = standard, 1 = macro)
v = run status (0 = stopped, 1 = running)
u = pressure board present = 0; otherwise 1
ID
OK,vx.xx SR3O firmware/ Identifies the pump type and EPROM revision x.xx
UPxxxx
OK/
Sets the upper pressure limit in psi. The maximum value for xxxx is 5000 for the plastic head or
6000 for the steel head; the minimum value is the lower limit plus 100. The value must be
expressed as four digits, i.e., for 900 psi xxxx = 0900.
LPxxxx
OK/
Sets the lower pressure limit in psi. The maximum value for xxxx is the current upper pressure
limit setting minus 100; the minimum value is 0.
The value must be expressed as four digits, i.e., for 100 psi xxxx = 0100.
SF
OK/
Puts the pump in fault mode. Turns on the FAULT LED and stops the pump immediately.
RF
OK,x,y,z/
Reads the fault status, where:
x = motor stall fault (0 = no, 1 = yes)
y = upper pressure limit fault (0 = no, 1 = yes)
z = lower pressure limit fault (0 = no, 1 = yes)
KD
OK/
Disables the keypad. (Default status at power-up is enabled.)
KE
OK/
Enables the keypad.
PCxx
OK/
Sets the pressure compensation value, where xx = the operating pressure (in psi divided by 100),
i.e., for 0 psi xx = 00, for 5000 psi xx = 50.
RC
OK,x/
Reads the pressure compensation value in hundreds of psi, i.e.,
(x or xx)
for 0 psi x = 0, for 5000 psi xx = 50.
HTx
OK/
Sets the pump head type, where:
x = 1 for a stainless steel 12 mL/min. pump head
x = 2 for a plastic 12 mL/min. pump head
x = 3 for a stainless steel 50 mL/min. pump head
x = 4 for a plastic 50 mL/min. pump head
x = 5 for a stainless steel 6 mL/min. pump head
x = 6 for a plastic 6 mL/min. pump head
The pump is stopped and the pressure compensation and pressure limits are initialized when the
head type is changed.
RH
OK,x/
Reads the pump head type, where:
x = 1 for a stainless steel 12 mL/min. pump head
x = 2 for a plastic 12 mL/min. pump head
x = 3 for a stainless steel 50 mL/min. pump head
x = 4 for a plastic 50 mL/min. pump head
x = 5 for a stainless steel 6mL/min. pump head
x = 6 for a plastic 6 mL/min. pump head
